3 Claims. ,(ol. 273-45) My invention refers to improvements themanufacture of billiards and pool-table and more particularly to'theconstruction of thebed as well as the parts connected with'the same.

.5 Billiards and similar appliances usually comprise a woodenbase-structure, a suitably reinforced frame supported .by the former anda playing-plate or bed, forwhich slate, marble or similar substances areused and which is supported by a frame-structure.

In some cases a wooden frame-structure duly reinforced in longitudinaland transverse direction is used for directly supporting the plate orbed., Base-struc tures made of a'metal such asiron have also beensuggested heretofore.

The cushion holders which, when made of wood, must be very voluminous,are usually connected with the plate or bed by means of screws.

Now on beds made of marble the rollingball produces a hard sound andforthis reason billiards have been usually equipped witha bed orplaying-plate of slate; Slate, however, is a comparatively soft materialof laminated structure and therefore very liable to become damaged,which is particularly the case during transport. Nevertheless slate isgenerally preferred and chiefly employed in the construction ofbilliards beds orplates mainly because the connection of the same withthe cushion or the abutting cushwhich is possible only with the aid ofnuts inbores for the screw threads break away and become inaccurate inconsequence of the parts concerned being repeatedly taken to pieces,when the cloth is renewed or its proper tension is reestablished. a r

The above-mentioned various drawbacks of the known complicated wooden ormetallic billiard base-structures as well as of the fastening of theplaying-plate orbed are obviated according to the present inventionthereby, that the playingsurface, plate or bed, upon which the game isexecuted, is made of metal, as for instance castiron, steel, light metalora metal alloy and of course afterwards covered with cloth'in the usualmanner. The metal plate may be provided with reinforcing ribs and mayconsist of one piece or may be composed of a plurality of pieces.

Theinvention is illustrated diagrammatically and by way of examplein theaccompanying surface of the bed. 1 areprojections 5 (Figs.

The rubber cushions 3 are inserted into the frame formed bysaid ledges, as shown in Fig. 3. Theprofile of the side rails may bechosen as desired. On the bottom 1 and 3) to which the legs 6 aresecured by means of screws 10. The legs may consist of any desiredmaterial. The playing plate may also consist of several parts.

The advantages presented by this construction, as well as by the use ofmetal for the playing plate and for the cushion frame areextraordinarily numerous.

Slate plates of such a quality and such a thickness as requisite for thepurpose in view are obtainable only in very few countries, whereas thereare nearly everywhere foundries and machine works, wheremetal platesuited for said purpose can be made.

Assembling the members constituting my pres- 35 ent improved billiard isvery simple and can be effected also by unskilled hands. I

In the case of a large billiard it is possible to reduce the weightthereof considerably by using a light metal for the playing bed and byomitting all separate supporting members'for said bed,

which is rendered possible by thelparticular construction described;that lesser weight facilitates cushions, retensioning the cloth, and thelike can be carried out far more easily and in a shorter, time than ispossible with billiards of anyof the known constructions.

No other material than metal renders it posemployed for said beds.

whatever, the balls run noiselessly, and the very,

sible to manufacture the playing plate so plane, accurate, properlyright-angled, and lasting.

The metallic playingfbedpresents unforeseen advantages over all othermaterials up to now There is no resonance the assemblage of the membersconstituting the billiard is greatly facilitated-landing) insertedinutsare required.
